Fig. 3 is a transverse section/on theline 3-.-3 ofFig. 1.

Fig.A L `is a Vdevelopment ofthe barrel blank, and v Figzb` is a sectional detail of the head.

I have indicated at 1 a barrelblank` which preferably consists of` a thin sheet ofqinaterial, such as' steel,v which is provided With a longitudinal series of spaced" corrugations 2 and 2 ali'ordingllstiffening ribs extending oirculnferentially of the barrel when the body blank-isrolled; to. shape about a, vertical axis andthelverticaledges ofQ'the ,blank overlapped detaohably connected toeach oth'e. 1

Inathet 4embodiment l selected as illustra-` tive ofthe principles of my invention, one verticalv .edge ofthe #blank is provided with a longitudinallys extendingl troughflikegrib 3v which is formed -therein4 ,by pressing out the material of1 the blank` adjacent said edge. v` The oppositef Vvertical f edge,` of a said blanklis providedvvithla similar :rib-4L which when;l the blank is rolled to shapefabout a vertical`r axis is positioned, opposite the with my raised rib 3.

The rib 3 is. provided as `here shown, with a spaced `series-of horizontally dise posed .tongues or lugs adapted-to enter a similar series ofslots-6 formed in` the ribAV at thelopposite` vertical edge ofthe blank,J as clearly shown `in Fig. 3, When said edges are overlapped-` The 'lugs 5 are stampedout of ythe ribs l 3 inT suchj manner. as towleave` a `pair of alined *openings1 5 at ,each end of the horizontally-prejecting Webz of metal constituting-the lug ,proper and v.vvhiclr Web enters the corresponding slot u6 in a the l rib 4` when the verticall edges' of :the-:blankjare overlapped,k j e The overlapping edges ofathewblank are connectedgby aflocking. key 7 which Ais entered endvvise throughethe* openingswat the ,base of-.fthe lugs 5, and is preferably provided t at oneI 4endvlyvith u a n bent l handle portionby 4means of` whichxtheiikey `may be inserted-,through--and jvvithdrawn Sage opgelegdThesen? islthus disposed.:

inside the barrel and is protected by the barrel body. Preferably, the key is so inserted as to dispose its bent end 8 within one of the circumferential corrugations 2 of the barrel body, as appears in Fig l.

The barrel is covered at one or both ends with a sheet metal head 9 which is preferably provided with an annular attaching Hange l adapted to be crimped over the barrel end, and if desired, also riveted thereto as indicated at l1.

VThe barrel therefore consists of a sheet metal body blank which is adapted to be rolled to sha-pe and connected along its overlapping vertical edges to provide an wopenended cylinder, the ends of which are closed by the flanged heads 9, and the overlapping edges are detachably united by the lug and slot arrangement 5 and 6 and removable key 7. This construction reduces the cost of manufacture to the minimum while at the same time providing a container which may be readily set up and collapsed.

In many cases no fastening members for the flanged head 9 will be required. The flange 1 0 may be driven over the lo7 bead 2 which lies nearest the top and bottom of the barrel and such frictional attachment is suiiicient in many cases. Y

As shown in Fig. l and in the enlarged sectional detail in Fig. 4 the'head proper 9 is provided with an annular reversed flange consisting of an upturned portion 9 and a dependingv outer flange 92. This forms a convenient chine for handling andy also a tight and strong joint. The end edges of the barrel receive the top entering the narrow groove or fold formed between the fianges 9 and 92. The heads 9 may be driven on the barrel edges which wedge tightly into the groove or channel of the head down to and partly wedging over the ribs 2.

As indicated above I prefer in most instances to use a fastening suc-l1 as a rivet or bolt passing through the flanges 9 and 92V and through the interposed barrel edge.

The arrangement of the ribs may be varied and other vertical ribs employed, but the marginal ribs 3 and l are particularly important as strengthening the barrel in the region of its overlap and as making possible a tight joint.

Various modifications in the form and con` struction of my device may obviouslybe resorted to without departing from thel spirit of my invention if within the limits of the appended claims.

What I therefore claim and desire to se-l cure by Letters Patent is:

1. A container comprising a blank of sheet material having vertical corrugations on its edges and adapted to be overlapped and united along said edges, said corrugations having a tongue and slot interlocking engagement with each other when overlapped and a locking device detachably engageable with said tongues for releasably maintaining the interlock.

2. A container comprising a longitudinally corrugated blank of sheet material adapted to be' overlapped and united along'two opposite edges, said edges having a tongue and slot in interlocking engagement with each other when overlapped, and a locking key detachably engageable with said tongues for releasably maintaining the interlock, said key having a handle portion disposable in one of the corrugations of the blank when the key is in locking position.

' 3. A container comprising4 a blank of sheet material adapted tobe overlapped and united along two opposite edges, said edges providedv with longitudinally extending ribs adapted to fit one within the other when the blank edges are overlapped, one rib having a spaced series of horizontally projecting locking lugs and the opposite rib having a spaced series of locking slots adaptedt'o receive said'lugs, and a locking key insertible endwisebeneath said lugs to detachably interlock the overlapping edges of the blank.

4. A container comprising a blank of sheet material adapted to beoverlapped and united. along two opposite edges, said edges blank edges are overlapped, one rib having a spaced series of horizontally projecting locking lugs and the opposite rib having a spaced series of locking slots adapted to re-4 ceive said lugs, .there being openings between said lugs and' the rib from which they are opposite edges, said edges provided with longitudinally. extending ribs adapted to fit one within the other when the blank edges are overlapped, one rib Vhaving a spaced series of. horizontally projecting locking lugs and the opposite rib having a spaced series of locking slots adapted to receive said lugs, there being openings between said lugs and the rib from which they are formed, and a locking key insertible endwise through said openings to detachably interlock thev overlapping edges of the blank, said key bent ,at one endto provide a handle adapted'to lie within one of the corrugations of the body blankwhen the key `is in locking position.

6. A container comprisinga flexible body portion having interlocking edges and having an annular groove adjacent one end thereof, and an end closurev comprising a depressed head having'a reversely folded rim providing` an upturned inner portion 95 provided with longitudinally extending ribs adapted to fit one within the other when the' and a downturned outer portion, the fold of said rim receiving the end edge of said flexible body portion, and the free end of said downturned outer portion of thev rim being frictionally engaged in the annular groove of said flexible body portion.

,7. A container comprising a flexible body portion having interlocking edges and having an annular groove adjacent one end thereof, and anend closure comprising a depressed head having a reversely folded rim providing an upturned inner portion and a downturned outer portion, the fold of said rim receiving the end edges of said flexible body portion, and the free end of said downturned outer portion of the rim being frictionally engaged in the annular groove of said flexible body portion, and fastenings passing through said inner and outer folds of the rim and the included end edge of said flexible body portion.

8. A container comprising a blank of sheet material adapted to be overlapped and interlockingly connected along two opposite edges, said edges having interlocking portions mutually engageabl-e with each other when the blank is overlapped, and a locking device disposed wholly within the container and detachably engageable with said interlocking portions at the blank edges for releasably maintaining the interlock.

9. A container comprising a blank of sheet material adapted to be overlapped and interlockingly connected along two opposite edges, and a locking device disposed wholly within the Vcontainer and detaohably engageable with said edges upon relativeV endwise movement thereof, for releasably maintaining the interlock.

l0. A container comprising a blank of sheet material adapted to be overlapped and united along two opposite edges, said edges having a tongue and slotinterlocking engagement with each oth-er when overlapped, and a locking device disposed wholly within the container and detachably engageable with said tongues for releasably maintaining the interlock.

In testimony whereof I affix my signature in the presence of two witnesses.
